Mosquitos Installed on at a Methane Seep

A "Mosquito" flow meter (far left) and osmotic fluid sampler (far right) are installed in an active methane seep at Southern Hydrate Ridge. A second Mosquito, colonized by organisms, awaits recovery. These instruments provide fluid chemistry information, as well as calculations of fluid flow in and out of the seafloor. Photo credit: NSF-OOI/UW/CSSF; Dive R1772; V14.
